京津冀一体化下生产性服务业的影响因素研究——以河北省为例

Research on the influencing factors of producer service industry in Hebei Province under the background of Beijing-Tianjin-Hebei integration——Take Hebei Province as an example

为了充分实现河北省生产性服务业对经济的带动作用。采用广义可行最小二乘法及门槛模型,研究河北省生产性服务业的影响因素。结果表明:工业化水平、经济发展水平等七个因素对全省生产性服务业有显著推动作用;将11个市分成与京津是否接壤两组检验,与整体回归结果存在差别,说明京津对河北生产性服务业发展存在不同影响;工业化对生产性服务业存在拉动和挤出作用,整体拉动强于挤出,但并非简单线性关系,而是随着工业化水平提高,促进作用降低。

In order to realize the leading role of the productive service industry in Hebei Province.The generalized feasible least squares method and the threshold model are used to study the influencing factors of the productive service industry.The results show that seven factors,such as the level of industrialization and the level of economic development,have a significant role in promoting the province’s productive service industry.The 11 cities are divided into two groups to test whether they are adjacent to Beijing and Tianjin,which is different from the overall regression results,indicating that Beijing and Tianjin have different influences on the development of Hebei’s productive service industry.;Industrialization has pulling and extrusion effects on the producer service industry.The overall level of industrialization is stronger than extrusion.It is not a simple linear relationship,but with the improvement of the level of industrialization,the promotion effect is reduced.This research has certain practical reference significance for the development of Hebei Province.
